Abstract

elemento óptico. um elemento óptico incluindo da primeira à quarta células de cristal líquido. cada uma dentre a primeira e a quarta células de cristal líquido inclui um primeiro substrato no qual um primeiro par de eletrodos transparentes em formato de pente está disposto, e um segundo substrato no qual um segundo par de eletrodos transparentes em formato de pente está disposto. uma direção de extensão do primeiro par de eletrodos transparentes em formato de pente é ortogonal a uma direção de extensão do segundo par de eletrodos transparentes em formato de pente. entre duas células de cristal líquido diferentes da primeira à quarta células de cristal líquido, um dentre o primeiro par de eletrodos transparentes em formato de pente de uma célula de cristal líquido e um dentre o segundo par de eletrodos transparentes em formato de pente da outra célula de cristal líquido são eletricamente conectados entre si.
